Subject: [PATCH 0/5] regulator: mp8859: add driver for DC/DC converter used on rk3399-roc-pc board
Date: Mon, 6 Jan 2020 22:16:23 +0100 [thread overview]
Message-ID: <20200106211633.2882-1-m.reichl@fivetechno.de> (raw)
On rk3399-roc-pc board a voltage regulator MP8859 from Monolithic Power Systems
is used to supply the 12V power line. This delivers 5V as a default value after
boot. The voltage is controllable via I2C.
Add a basic driver to set and get the voltage of the MP8859 and add a matching
node with fixed 12V in the DT of the board.
Markus Reichl (5):
regulator: mp8859: add driver
regulator: mp8859: add config option and build entry
dt-bindings: add vendor Monolithic Power Systems
dt-bindings: regulator: add MPS mp8859 voltage regulator
